[0042] The structure of the POS machine according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Reference Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the POS machine structure provided in the embodiment of the present invention includes: a housing 10, a main control board 20, a mounting bracket 30 and an antenna 40. The main control board 20 is arranged in the housing 10 to be limited by the housing 10 at the edge; the mounting bracket 30 is arranged in the housing 10 and interlocks with the main control board 20; the antenna 40 is attached to the side of the mounting bracket 30, and is used to electrically connect the antenna 40 with the main control board 20 when the mounting bracket 30 is fixed to the housing 10. Among them, the main control board 20 is provided with a connection contact 201, and the antenna 40 extends from the side of the mounting bracket 30 to the inside of the mounting bracket 30 and has a gold finger 401 facing the connection contact 201. When the mounting bracket 30 is fixed to the face shell 11, the gold finger 401 is in contact with the connection contact 201.

[0044] In this embodiment, in order to facilitate the contact between the antenna 40 and the main control board 20 to be simpler and tighter, the gold finger 401 of the antenna 40 is arranged to be opposite to the connection contact 201 on the main control board 20, so that when the mounting bracket 30 is installed, the antenna 40 can be connected to the main control board 20 simultaneously, so that the process installation of the antenna 40 is simpler and the electrical contact is better; wherein, by arranging the antenna 40 on the mounting bracket 30, the spacing between the mounting bracket 30 and the main control board 20 in the housing 10 can be smaller, avoiding the conventional antenna 40 in the housing 10. The problem of a large gap is caused by being on the rear shell 12; when installing, the mounting bracket 30 can be covered on the main control board 20, and can be interlocked with the main control board 20 to ensure better overall stability; it can be understood that the main control board 20 can be equipped with a central processing unit CPU, connected to the antenna 40 signal and can receive SIM card data, etc., and then can be responsible for processing various instructions and data of the POS machine. An auxiliary circuit board can also be arranged in the shell 10, and the auxiliary circuit board is mainly used to realize functions such as magnetic stripe card reading and NFC contactless payment.

[0045] The POS machine structure provided by the present invention arranges the antenna 40 on the side of the mounting bracket 30. After the mounting bracket 30 is fixed to the shell 10, the antenna 40 can be electrically connected to the main control board 20, thereby avoiding a large distance between the antenna 40 and the main control board 20, allowing the antenna 40 to have better electrical contact with the main control board 20, thereby improving the signal function of the antenna 40.

[0046] Reference Figure 3 , Figure 5 and Figure 7 As shown, the shell 10 includes: a front shell 11, a rear shell 12 and a display screen 13. The rear shell 12 is fixed to one side of the front shell 11 and together with the front shell 11, the main control board 20 and the mounting bracket 30 are enclosed; the display screen 13 is arranged on the other side of the front shell 11 and is electrically connected to the main control board 20.

[0047] In this embodiment, when assembling the POS machine, the main control board 20 and the auxiliary circuit board can be fixed to the face shell 11 first, and then the mounting bracket 30 can be covered on the main control board 20, and further formed with the face shell 11 for installation (such as pressing into place and / or locking and / or screw locking), and finally the rear shell 12 is covered on the mounting bracket 30 and fixed to the face shell 11, so that the main control board 20, the auxiliary circuit board and other components can be enclosed by the face shell 11 and the rear shell 12, ensuring better overall consistency; wherein, the display screen 13 can adopt a touch screen, etc., and can be connected to the main control board 20, so that the main control board 20 can receive the touch signal of the display screen 13 to realize various functions.

[0048] In one embodiment, both sides of the face shell 11 have partially protruding side walls, which can form a preliminary limit for the main control board 20 in the width direction (for example, so that the main control board 20 cannot be swayed or dropped left or right at will), and then the mounting bracket 30 is covered on the main control board 20 and further interlocked with the main control board 20. At the same time, the mounting bracket 30 is also connected to the side walls of the aforementioned face shell 11 and installed on the face shell 11.

[0049] In some embodiments, the two sides of the face shell 11 in the width direction are provided with plugging grooves 111, and the plugging grooves 111 extend along the thickness direction of the face shell 11 for the mounting bracket 30 to be plugged in. It can be understood that in some embodiments, the plugging grooves 111 on both sides of the face shell 11 in the width direction are formed on the side wall surface protruding from the face shell 11. The plugging grooves 111 are used for more stable installation with the mounting bracket 30, and for products with a split bracket (mounting bracket 30), the product structural stability and the efficiency of the product installation process can be enhanced.

[0050] In a preferred embodiment, the protrusion 302 is preferably a convex strip, which extends along the thickness direction (z-axis direction) of the mounting bracket; the insertion groove 111 is preferably a strip groove, one end of which includes a plug-in entrance, and the strip groove has a groove channel, and also has a groove on the side to cooperate with the external convex strip to slide. The convex strip slides into the strip groove along the z-axis direction under the cooperation of the above structure, and after sliding into place, the entire convex strip and the entire strip groove are inserted in the xy plane, forming a better locking effect.

[0051] Furthermore, an embedding groove 112 is also provided on the edge of the face shell 11, the starting point and end point of the embedding groove are connected to the corresponding insertion groove, and the embedding groove 112 extends along the length direction and width direction of the face shell 11 at the edge of the face shell, and is embedded with the flange 304 formed on the edge of the mounting bracket 30.

[0052] In this embodiment, the embedding groove 112 can be formed along the x-axis (the length direction of the face shell 11) and the y-axis (the width direction of the face shell 11), and the plug-in groove 111 can be formed along the z-axis (the thickness direction of the face shell 11). When fixing the mounting bracket 30 to the face shell 11, the mounting bracket 30 and the face shell 11 can be plugged and fixed from the z-axis direction, so that the mounting bracket 30 can be limited and locked by the main control board 20 in the z-axis direction, and at the same time limited and locked by the embedding groove 112 in the x-axis direction and the y-axis direction, which makes installation simpler and more convenient.

[0053] Reference Figure 5 , Figure 6 and Figure 8 As shown, the mounting bracket 30 has a connecting portion 301, which is respectively spliced ​​on both sides of the width direction of the face shell 11, and each connecting portion 301 is formed with a protrusion 302 corresponding to the plug-in groove 111, and the protrusion 302 is used to be plugged with the plug-in portion to limit the movement of the mounting bracket 30.

[0054] In this embodiment, when installing the mounting bracket 30 and the face shell 11, the protrusion 302 can be slidably inserted into the insertion groove 111 in the z-axis direction, so that the mounting bracket 30 can be quickly fixed to the face shell 11 from the z-axis direction, and at the same time, the flange 304 on the mounting bracket 30 and the embedding groove 112 can be quickly engaged, so that the mounting bracket 30 can be quickly locked in the x-axis direction and the y-axis direction, thereby preventing the mounting bracket 30 from loosening and providing better stability.

[0055] Furthermore, each connecting portion 301 is also provided with a first hooking portion 303, which extends between the main control board 20 and the face shell 11, and is used to hook with the main control board 20, so that the main control board 20 can limit and lock the mounting bracket 30. When installing the mounting bracket 30, the two first hooking portions 303 can first abut against the edge of the main control board 20 to be pushed and deformed by the main control board 20. After the first hooking portion 303 enters between the main control board 20 and the face shell 11, the first hooking portion 303 is restored and hooked on the main control board 20, so that the main control board 20 limits and locks the mounting bracket 30, thereby preventing the mounting bracket 30 from falling off in the z-axis direction during installation, and the installation is simpler and more stable.

[0056] Specifically, a second hooking portion 113 is provided on the front shell 11 , and the second hooking portion 113 extends between the main control board 20 and the rear shell 12 , and together with the first hooking portion 303 , limits and locks the main control board 20 . Among them, the second hooking part 113 can be provided with multiple ones, and they are located at the edge of the main control board 20. When the main control board 20 is installed, the main control board 20 can be directly pressed down to the bottom of the second hooking part 113, so that the second hooking part 113 can quickly buckle and lock the main control board 20, thereby preventing the main control board 20 from falling off in the z-axis direction during installation, and then the main control board 20 can be further fixed by screws or the like in the subsequent installation, so that the installation is more stable and reliable; it can be understood that the first hooking part and the second hooking part are designed to face each other from two directions, and the main control board is hooked and buckled from the upper and lower directions respectively, so that the face shell, the main control board and the mounting bracket form multiple layers of mutual fixation, so that the main control board is locked by the face shell, and a limit interlocking can also be formed between the main control board and the mounting bracket, so that the installation is simpler and more stable.

[0057] As a preferred embodiment, the first hook portion 303 has a guide surface 3031 facing the cover 11. When the mounting bracket 30 is plugged into the cover 11, the guide surface 3031 is pushed by the edge of the main control board 20 to force the first hook portion 303 to deform. Among them, the distance between the two first hooking parts 303 can be set to be slightly smaller than the width of the main control board 20, the guide surface 3031 can be set to an arc surface or a slope, and the two first hooking parts 303 are relatively arranged, and then when the mounting bracket 30 is installed, the two first hooking parts 303 can first be abutted against the edge of the main control board 20, and pushed and deformed by the main control board 20 under the action of the guide surface 3031. After the first hooking part 303 enters between the main control board 20 and the face shell 11, the first hooking part 303 is restored and hooked on the main control board 20, so that the main control board 20 limits and locks the mounting bracket 30. Therefore, the first hooking part 303 and the second hooking part 113 are respectively locked on both sides of the main control board 20, so that the main control board 20, the mounting bracket 30 and the face shell 11 can be locked with each other, and the installation is simpler and the stability is better.

[0058] Optionally, the mounting bracket 30 is provided with a plurality of mounting openings 305, and the plurality of mounting openings 305 correspond to the components on the main control board 20. Among them, the plurality of mounting openings 305 can respectively correspond to the installation of components such as cameras, speakers, USB interfaces, etc., so that after the mounting bracket 30 is fixed to the face shell 11, each component can be correspondingly embedded in the mounting opening 305, so that the overall installation positioning is more accurate and the consistency is better.
